(1) This dataset is a Qinghai-Tibet Plateau carbon flux dataset compiled from published literature, covering parameters such as air temperature, soil temperature, precipitation, and ecosystem productivity. (2) This dataset is developed based on field-measured eddy covariance data, adopting internationally recognized standard processing workflows for eddy covariance datasets. The standard processing steps include: outlier removal, coordinate rotation, WPL correction, storage term calculation, removal of observations with concurrent precipitation, threshold filtering, outlier elimination, u* correction, missing data interpolation, flux partitioning and statistical analysis. This dataset also includes model simulation data calibrated against the eddy covariance dataset. (3) This dataset has undergone strict data quality control, with a data missing rate of 37.3%, and the missing values have been filled via interpolation. (4) This dataset holds scientific significance for understanding the carbon sink function of alpine wetlands, and can be applied to the calibration and validation of mechanistic models and other related research scenarios.
